T0 cir/ZZ whom, it may concern:`

Be it known that I, VINCENT A. FABRYCKI, a citizen of the United States, residing at Lasalle, in the county of Lasalle, State of Illinois, have invented certain new and useful Improvements in Detachable Shoe-Heels, of which the following is a specification.

The object of my invention is to provide for the ready and secure attachment of the heel to the shoe or its detachment therefrom by mechanism controlled from the inside of said shoe, and to this end I secure to the shoesole a base-plate having a series of tongues or projections which are engaged by lockingbolts which are shot transversely through said projections and retracted therefrom by a rackand-pinion arrangement operated by a key, the above mechanism being carried by a counterpart plate also having tongues or projections which engage with thoseof said baseplate and are locked thereto by the bolts when the latter are actuated, all as hereinafter de scribed and claimed.

In the drawings, Figure l is a side elevation, partly broken away, of a shoe embodying my invention, the interlocking apparatus being indicated in a general way by dotted lines. Fig. 2 represents the sole or base-plate in top plan and longitudinal section. Fig. 3 represents in top plan and edge'elevation the arrangement of said plate in relation to the sole and insole. Fig. 4 is a top plan View of the heel-plate and its attachments in position upon the heel proper. Fig. 5 represents details of said heel-plate, in top plan Vand longitudinal section, stripped of all movable accessories. Fig. 6 gives like details of the blank heelbefore the plate is attached thereto, and Fig. 7 comprises in detail the various movable parts of the mechanism detached and individualized. p

Referring now to said drawings, A represents the shoe proper, and B the detachable heel thereof. This heel may be built up of leather lifts, molded of rubber or other material, cut out of a wooden block, or otherwise y constructed. As a blank it is formed with a -sad socketand having peripheral upstanding flan ges c of the height of said socket and the perforations eX and perfor-ations cx, one "with the other, is applied thereto by passing said lugs through said perforations in the sole `from above and securing the plate to the top of the sole by riveting or otherwise.

As thus far constructed if the heel is applied to the shoe the lugs of the sole-plate will enter the bosses of the heel-plate and heel and shoe will t together, as represented in Fig. l, but will not be held together in the absence of other agencies. To provide, therefore, for locking the parts together and readily unlocking them for separation, sliding bars F F are applied to the heel-plate and confined thereto between the flanges cby a strap f in such manner that when actuated their bolting-fingers f'f2, &c., will engage in the registered perforations 0?( and ex of the bosses of the one plate and the lugs of the other after the lugs e have-entered the recesses in bosses c c2, dac., and thereby prevent the parts being separated. In the present case I have shown two locking-bars, one of which has three forwardly-projecting bolting-ugers f', f2, and f3, to respectively engage the two bosses c and c2 at one side of the heel, and one end bolt f3, to engage the boss cs at the rear center of said heel, and the other being provided With two bolting-iingers f4 and f5 to engage the two bosses c4 and c at the opposite side of said'heel from theirst bar. The number of bolting-iingers and their arrangement, as Well as the number of sliding bars or bolts, will of course depend upon the nu mber and disposition of the bosses or lugs.

In order to operate the bolts simultaneously, each sliding bar is formedwith a rack g along the edge opposed to the other bar, and with these racks engages a pinion G, having IOC . also in the aforementioned strapf, bridging and conning said bars. The squared head of the key-stem projects upward above the bridge-strap, so as to be reached by a key H, inserted through a hole h in the sole-plate and either covered by the insole or matching a perforation h therethrough. If, as in the former instance, the orifice h is covered by the insole, the same is not securely fastened to the sole-plate,but is loosely fastened,so the same can be readily lifted and access gained 'to the orifice 71.. Since the bars must move in reverse directions under the interengagement of the pinion, the bolting-tingers of the bar F are returned upon the bar itself to point to the front, while those of the other point to the'rear.

Guide-pins I and stops 2 2 are provided to aid the bridge-strap in keeping the sliding bars up to the pinion, and fromv one of said bars F a retracting-spring is extended to the corresponding pin or other suitable point of attachment and acts toihold the bolts normally closed or to return them to a closed position when once withdrawn therefrom.

For the purpose of applying the heel to the shoe the bolts are first withdrawn by means of the key sufficiently to open the bosses, the two members then tted together, and the key released or withdrawn, when the spring will immediately shoot the bolts home, completing the fastening. To detach the heel, the bolts are simply withdrawn by means of the key, when the heel will drop off.

While I have described the bosses as formed seams ing bars and bolts should remain on the heelplate whatever the disposition of the lugs and bosses. It is evident also that the spring whereby the bolts are automatically shot home may be omitted and said boltsboth advanced and retracted by the key.

I claiml. The combination with a shoe-sole having lugs on its under face, of a detachable heel carrying recessed bosses for receiving said lugs, and spring-actuated sliding means carrying fingers engaging through said lugs and bosses, and means for actuating said means from the shoe-sole, substantiallyas described.

2. The combination ot the sole, the baseplate attached to said sole and having downwardly-projecting lugs and a perforation for the insertion of a key, the heel-plate attached to the seat of the heel and having recessed bosses to receive said lugs, the two sliding rack-bars having bolting-tingers to engage and lock said lugs and bosses, and the pinion engaging with the racks of said bars and having a key-stem registering with the perforation in the base-plate.
